We had one just like that and I had to let my husband cull it a few days agowhat the crossbeak looks like today. . ..she's thinnish, but still active eating and I try to isolate her to and feed her stuff she can scoop up. But I do not have much hope of her doing well in the long run. I know I should put her down, but I will take her to the vet for that, I just can't do it myself. =( I'm a coward, yes. She got some scrambled eggs yesterday and she ate some, she refuses to eat from my hand or allowing me to 'help' her at all. I don't think any amount of trimming or supplements are going to help her, it's not a little crossed, it's majorly crossed.
